[Detailed description of the invention] Books in the luxury goods field or food field Pieces of qualitatively flat objects, especially chocolate bars No packaging for chocolate bars or bar chocolates. Method 2 and device for packaging The present invention is applicable to essentially flat article pieces in the luxury goods field or the food field, particularly board chips. Regarding the method for wrapping chocolate or chocolate bars with packaging sheets, the same Sometimes an apparatus for carrying out this method is presented. Conventionally, all kinds of packaging materials A so-called tube packaging machine is used for packaging. In some cases, the wrapping sheet runs from the storage roller in the form of a notebook strip and is placed in the form of a notebook strip to be wrapped. The strip is mounted on a transport mechanism in which the sheet strip is moved in the same direction as the sheet strip. The tube is sequentially supplied to the above-mentioned tube edger by the row member at intervals, and then the sheet band is The pieces were folded around the respective parts and welded together at their longitudinal and transverse edges. child The synthetic notes used in this case must be particularly robust and flexible.

This is because the sheet must be expanded to cover different types of forming tools during processing. This is because it must be done.

In order to achieve the required hardness of the packaging, the work must be carried out with a wide spread of the material. No. This operation results in high consumption of packaging material and a relative reduction in machine efficiency. invite Particularly thin and heat-sealable aluminum sheets are often used as packaging materials. I can not use it.

However, such metal sheets are not suitable for sweet products, especially chocolate bars or chocolate bars. That's exactly what rate packaging is for.

The problem of the present invention (ri) is to eliminate the above-mentioned defects and to solve the specific load on each packaging sheet. Especially under the achievement of high mechanical efficiency and packaging machine consumption savings without costing the board Tubes are used for inner packaging of flat items such as chocolate or chocolate bars. The objective of the present invention is to create a method and apparatus that makes it possible to carry out bulk packaging.

Especially when the vertical seal is formed on the narrow side and the notebook is especially commonly used. Thin, heat-sealable molds that cannot be processed using a typical mold shoulder on a tube forming machine Packaging in which metal notebooks are used, which ensures particularly high tightness of the sealing seams. It is about creating work.

According to the present invention, the above-mentioned matters can be realized by combining the feeding of the sheet belt-like article with the belt-carrying member. This problem can be solved by directly combining the two in terms of time. Especially in this case, no For the purpose of conveyance, the band-shaped goods are I feel narrowed down.

According to the invention, packaging sheet strips, in particular aluminum sheets, can be cut according to their length.
